SLIP-NOSE ATTACHMENT FOR PLOWS.

E SPECIFICATION forming part of Letters Patent No. 239,135,.dated March22, 1881.

' Application filed December 18, 1880. (ModeL) To all whom it mayconcern Be it known that we, OHARLEs ANDERSON and JAMES OLIVER, of.South Bend, in the county of St. Joseph and State of Indiana,

have invented certain new and useful Improvements in Slip-NoseAttachments for Plows; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,

reference being had to the accompanying drawings, which form part ofthis specification.

Our invention relates to an improvement in slip-nose attachment forplows.

r 5 In Patent N 0. 223,751, granted to J. Oliver January 20, 1880, thenose portion of the share or point is furnished with a plain fiat seaton its upper side, and provided with a recess on its under side. Theslip-nose is provided with a jaw or extension, which is seated upon theplain flat seat of the point or share, and with a lip or projection thatfits into the recess on the under side of the point or share. This formof plow-point and slip-nose attachment is objec- 2 5 tionable for thereason that a joint is formed at the side of the nose, allowing of theentrance of soil and preventing the free working of the point. Further,the slip-nose is not provided with a sufficientlateral bracing, so thatundue strain is imparted to the fastening-bolt.

Again, we are aware that the nose portion of a plow-point has beenformed with a slit or recess, within which has been inserted the shankof aremovable nose. This construction 3 5 of plow-point is objectionablefor the reason that the divided or slitted nose portion of the share orpoint is liable to become broken in use, and thus destroy the entirepoint or share.

The object of our invention is to obviate c the defects andobjectionable features in plowin the claim.

In the accompanying drawings, Figure l is a plan view of a plow-pointprovided with our improved slip-nose attachment. Fig. 2 is alongitudinal vertical section taken through the plow-point andslip-nose. Fig. 3 is a trans- 5 verse vertical section of the same. Fig.4 is a view, in perspective, of the plow-point and slip-nosedisconnected from each other.

A represents the plow point or share, the nose portion of which isprovided with grooves a a on its upper and lower sides. Grooves a a areof any desired length and at the central portion of the nose, wherebythere is formed side walls or bearings, a, on each side of both theupper and lower grooves, a a.

Slip-nose B may be of any desired form on its forward or wearing end.Its rear end is furnished with the two jaws b b, which are adapted tofit snugly within the grooves a a on the upper and lower sides of thenose portion of the share or plow-point, the slip-nose B being securedin place by means of the bolt 0. The surface of the upper jaw is flushwith the upper surfacejfof Ethejplow-point, sojthat the workingorwearing surface of the latter is made. 7 5 smooth and unbroken. Bothjaws of theslipnose have an extended face-bearing on the web portion 1of the point or share,wherehy the slip-nose is firmly braced againstdisplacement byreason of upward or downward pressure on So the outer endof thejslip-n ose. i, The sidesfof the jaws b b fit against the idewalls, a a, of both the upper andlower grooves, andgthus prevent anylateral displacement of the slip-nose. By reason of the extended faceand side bearings of the jaws blbfonthe nose portion of the plowpointthe slip-nose is firmly held in position, and but slight strain is borneby the attachingbolt 0. Further, the nose portion of the plowpoint,being constructed without any slit or openingtherei n, is renderedstrong and durable.

In order to increase the durability of the slip-nose, the jawslb .b andcontiguous portion thereof are annealed; and the forward portion of theslip-nose protected against the anneal- 5 ing process, the line 00 m ofthe drawings indicatin g approximately the dividing-line between theannealed and the unannealed portions of the slip-nose. This processinsures strength and toughness of the metal forming the jaws roo videdwith two jaws practically equal in.

length, and which fit within said grooves, and are thus furnished withextended face-bearings on the web between said grooves, and

with extended lateral or side hearings on the side walls of the grooves,and a fastening-bolt 15 which extends through the two jaws and web,substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our handsthis 13th day of December, 1880.
